Sumatriptan Succinate
CAS Number 103628-48-4
USES: Sumatriptan is used to treat migraines. It helps to relieve
headaches, pain and other symptoms of migraines, including sensitivity to
light/sound, nausea, and vomiting. Prompt treatment allows you to get back
to your normal routine and may decrease your need for other pain
medications. Sumatriptan does not prevent future migraines or reduce how
often you may get a headache.

HOW TO USE: Read the Patient Information Leaflet available from your
pharmacist before you start using sumatriptan and each time you get a
refill. Ask your doctor or pharmacist if you have any questions.

Take this medication by mouth, with or without food, at the first sign of a
migraine. If there is no improvement in your symptoms, do not take any more
doses of this medication before talking to your doctor. If your symptoms are
only partly relieved, or if your headache comes back, you may take a second
dose after two hours or as directed by your doctor. Do not take more than
200 milligrams in a 24-hour period.

SIDE EFFECTS: Flushing, sensations of
tingling/numbness/prickling/heat, weakness, drowsiness, or dizziness may
occur. If any of these effects persist or worsen, notify your doctor or
pharmacist promptly. Chest/jaw/neck tightness can commonly occur shortly
after using sumatriptan. Only rarely are these signs of a serious condition.
However, you may not be able to tell it apart from a serious reaction
related to a lack of blood flow to the heart, brain or other parts of the
body. Seek immediate medical attention if any of these unlikely but very
serious (rarely fatal) side effects occur: chest pain, jaw/left arm pain,
fainting, fast/irregular/pounding heartbeat, vision changes, weakness on one
side of the body, confusion, slurred speech, sudden or severe
stomach/abdominal pain, bloody diarrhea.

PRECAUTIONS: Before using sumatriptan, tell your doctor or pharmacist
if you are allergic to it; or to other triptan drugs (e.g., zolmitriptan,
rizatriptan); or to sulfa drugs; or if you have any other allergies.

This medication should not be taken if you have certain medical conditions.
Before using this medication, consult your doctor or pharmacist if you have
a history of: heart disease (e.g., chest pain, heart attack), decreased
blood flow in the brain (e.g., stroke, transient ischemic attack), blood
circulation disease (e.g., ischemic bowel disease), uncontrolled high blood
pressure (hypertension), certain types of headaches (hemiplegic or basilar
migraine), liver disease.

MISSED DOSE: Take this medication only as needed when a migraine
occurs, as directed by your doctor. This medication should not be taken on a
regular schedule. Never increase your dose of this medication or take it
more often than prescribed by your doctor.
